F-Droid submission prep: fastlane metadata, build recipe, and FOSS (Steam-less) flavor

[gantoine]

Prepares Argosy Launcher for submission to F-Droid. Groups: media metadata in the app repo, a ready-to-copy fdroiddata build recipe, and a foss product flavor that builds without the prebuilt Steam dependency F-Droid rejects.

What's included

1. Fastlane media metadata (fastlane/metadata/android/en-US/)

• title, short_description (≤80), full_description (allowed-HTML subset), changelogs.
• icon.png (512×512, from argosy_icon.svg), generated featureGraphic.png (1024×500), and the 8 README screenshots.

2. fdroiddata build recipe (fdroid/)

• com.nendo.argosy.yml — recipe to copy into metadata/com.nendo.argosy.yml on GitLab. ABI-split blocks matching the versionCode override, submodules: true, VercodeOperation, stable-tag autoupdate, scandelete: [libs/maven], AntiFeatures: NonFreeNet. Targets the eventual v2.0.0 stable tag (versionCode is a documented placeholder to finalize at tag time).
• README.md — research findings, blocker analysis, and the GitLab submission workflow from fdroiddata's CONTRIBUTING.
• RFP.md — a filled-out Request For Packaging (optional alternative to the MR).

3. FOSS product flavor (full / foss)

• full (default): unchanged Steam build for GitHub releases; the six JavaSteam-backed classes move to app/src/full/.
• foss: no Steam library. No-op stubs in app/src/foss/ reproduce the public API shared code consumes plus the shared value types (SteamModels.kt). The ~30 non-library Steam files stay in src/main. Removes the prebuilt libs/maven jars and the non-free depot downloader from the F-Droid artifact.

This branch does not change versionCode/versionName — the version is owned by the 2.0 release line (see below).

Why the FOSS flavor

Steam integration depends on prebuilt jars in libs/maven (a non-Maven-Central MIT fork of JavaSteam that also fails to build on JitPack). F-Droid's scanner rejects committed binaries regardless of license, so the F-Droid build ships without Steam via foss.

Verification

• kspFossDebugKotlin (Hilt DI graph) and Kotlin frontend type-checking of the full foss source set both pass with 0 errors.
• A full assembleFossRelease was not run to completion locally: this app's clean Compose compile is pathologically slow (StabilityInferencer), on the order of the ~2–2.5h the release-line CI builds already take. It terminates; it's not the flavor change. The foss and full Compose workloads are effectively identical.
• The Steam data layer is byte-identical between main and the 2.0 branch (ui-redesign-beta), so the stubs match 2.0's call sites too.

Confirmed during research

• sigil submodule: pure C, MPL-2.0, builds from source via CMake/NDK — no Rust, no blobs.
• License: GPL-3.0-only. api.argosy.dev social layer → NonFreeNet (titledb/cheats are build-secret-gated and inert in a source build).

Folding into 2.0 (how this reaches F-Droid)

This PR targets main; the F-Droid work is folded into the 2.0 line (ui-redesign-beta, which already contains main). After merge:

1. Forward-merge main into ui-redesign-beta, then tag/push v2.0.0 off it (the tag must contain fastlane/ + the foss flavor).
2. Set the recipe's placeholder versionCode (1000302/2000302) to <abi>*1_000_000 + <2.0.0 base versionCode>, and add changelogs/<2.0.0 codes>.txt.
3. On a GitLab fdroiddata fork, copy fdroid/com.nendo.argosy.yml → metadata/com.nendo.argosy.yml, run fdroid lint / fdroid build, then open the "New App: com.nendo.argosy" MR.

Greptile Summary

This PR prepares the app for F-Droid distribution. The main changes are:

• Added full and foss product flavors.
• Moved JavaSteam-backed code into the full source set.
• Added no-op Steam stubs for the foss source set.
• Added Fastlane store metadata and F-Droid packaging files.

Confidence Score: 4/5

The FOSS flavor needs fixes around Steam-facing behavior before merging.

• The Gradle flavor split and dependency scoping look coherent.
• The F-Droid listing can advertise Steam support that the FOSS build removes.
• A reachable Steam sync action can wait on state that the FOSS stub never updates.

Important Files Changed

Filename	Overview
app/build.gradle.kts	Adds the distribution flavor split and limits JavaSteam dependencies to the full flavor.
app/src/foss/kotlin/com/nendo/argosy/data/steam/SteamLibraryManager.kt	Adds an inert Steam library manager for FOSS, but reachable sync callers can observe a permanently idle state.
app/src/foss/kotlin/com/nendo/argosy/data/steam/SteamService.kt	Adds a minimal FOSS Steam service stub that binds but never connects.
app/src/foss/kotlin/com/nendo/argosy/data/steam/SteamContentManager.kt	Adds inert Steam download and discovery state for the FOSS flavor.
app/src/foss/kotlin/com/nendo/argosy/data/steam/SteamModels.kt	Adds FOSS copies of the Steam state and value types used by shared code.
fastlane/metadata/android/en-US/full_description.txt	Adds store description metadata, including a Steam feature claim that does not match the FOSS artifact.
fdroid/com.nendo.argosy.yml	Adds a ready-to-copy F-Droid recipe for future v2.0.0 FOSS builds with ABI-specific version codes.
